One thing to look at

0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Generates vendor-neutral root-cause-analysis (RCA) hypotheses from incident symptoms and recent changes, producing a prioritized investigation plan.

1.4 KB, as published. Nobody here has run it

When to invoke

After an outage/incident when you have symptoms and a change log but no confirmed cause.
You want a structured, testable list of hypotheses with next steps.

Inputs needed

--incident: JSON describing impact window, symptoms, and affected components.
--changes: JSON list of recent changes (deploys, config, infra).
Optional: --out: Path to write hypotheses JSON.

Workflow

Load incident and change entries.
Extract keywords from symptoms/components.
Score each change by time proximity and keyword overlap.
Generate hypotheses:
- “Change X caused symptom Y via mechanism Z”.
For each hypothesis, produce:
- quick checks (logs/metrics/flags)
- deeper validation
- rollback/mitigation options
Output top hypotheses sorted by score.

Output format

JSON with:

incident_summary
hypotheses: list with rank, score, hypothesis, evidence, next_steps

Guardrails

Do not claim certainty; hypotheses must be framed as testable.
Avoid blaming individuals; focus on systems.
Keep guidance vendor-neutral (no tool-specific commands).
